Are those exposed through the libpq interface?
If not, is there a way to use the libpq interface for most operations, 
and only for the rest to use whatever it is you are suggesting I use 
(couldn't locate it in the docs, yet)

Funnily enough, mandating protocol version 3 is not my problem at the 
moment. I may have to do so for a host of other reasons as well. I 
guess, if you want to use an earlier version of the database, you will 
have to make do with the ole db to ODBC interface.
